Research suggests that subtle environmental modifications ('nudge theory') can promote healthy behaviors, such as hygiene practices, more effectively than direct rules and signage. To investigate this, a researcher conducted an observational study of hand sanitizer use in a public hospital corridor. Two identical sanitizer dispensers were located near each other: one had a bright green arrow printed on the floor leading directly to it, and the other had no floor markings.
Observations of sanitizer use were recorded during a busy clinical shift from 1:00 PM to 4:00 PM. The data showing how many times each dispenser was used by visitors and hospital staff is presented in the table below.
Table showing the number of times each sanitizer dispenser was used by Visitors and Staff:
| Visitors | Staff | |
|---|---|---|
| Sanitizer with floor arrow | 18 | 24 |
| Sanitizer without floor arrow | 8 | 22 |
Outline two conclusions that can be obtained from the data collected in this study.
